Franzen is on “concussion protocol” following a high hit from Tampa Bay defenseman Radko Gudas during a 3-0 loss in Detroit on Sunday. The incident occurred early in the second period and, after Gudas went unpenalized, Franzen blew up at officials and earned a unsportsmanlike conduct penalty.

Franzen then left the game and didn’t return, finishing with just 6:50 TOI.

“All those guys that get bumped in the head — you know what it’s like in the league now? They’re gone forever, it seems like. So I don’t know what that means,” Babcock told the Detroit Free Press following the game. “I don’t know, protocol-wise, what’ll happen. We’ll figure that out.”

It remains unclear if the Wings will recall a forward from AHL Grand Rapids to replace Franzen in the lineup. The 33-year-old Swede has nine goals and 22 points in 30 games this year, averaging just over 17 minutes per night.
